you can pull off the un burnt and repack it with more fresh but honestly i dont think its worth it, tobacco is not that expensive per bowl. honestly like 30 cents for a bowl of nakhla, even only 50 cents for a bowl of SB (in a mod bowl, probably 5-10 cents more for a standard egyptian, havent counted the number of egyptian bowls yet)

im all for saving money but why save 5-10 cents at the expense of probably off tasting smoke
